Purification of sucrose esters of fatty acids by a method of ultrafiltration

ABSTRACT

A sucrose ester product mixture containing sucrose esters, glycerides and free fatty acids, all fatty acid groups having carbon chains of 2-22 carbon atoms, has been separated into a concentrated sucrose ester fraction and a concentrated glyceride-fatty acid fraction by ultrafiltration through a polysulfone, anisotropic, microporous, membrane which normally partitions solutes of a molecular weight above 10,000 from those below a molecular weight of 10,000.
